class message
#include <message.hpp>

Optimizes the formatting for prepending and/or appending strings to the original message.

It keeps all the modified message in one string. Useful if some formatter needs to access the whole string at once.

reserve() - the size that is reserved for prepending (similar to string::reserve function)

Note : as strings are prepended, reserve() shrinks.
